BURNERS Henry Kccbler, Secaucus, J. v 'Application May 15,1940, Serial nassasws 3.;Claims. (01.236-99) This invention relates to thermostatic control for stove and range oil burners.

An object of this invention is :to provide a thermostatic control of the character described provided with highly improved means for regulating the temperature desired in the room.

Yet another object of this invention is to provide a compact and durable thermostatic control of the character described, which shall be relaand arrangement of parts which will be exempli-,

fied in the construction hereinafterdescribed,and

of which the scopeof application will be indicated in the following claims;

In the accompanying drawing. inwhich is shown one of the; various possibleiillustrative embodiments of this invention,

The single figure of the drawing is a side elevational view of athermostatic control embodying the invention, in conjunction-with a stove, and with parts in cross-section.

Referring now in detail to the drawin l3 designates a stove or range, andll designates a thermostatic control for the fuel for the burners for the stove or range III.

The thermostatic control H comprises a vertical pipe l2, to the lower end of which is screwed a valve housing chamber I3. has a bottom wall l4, formed with an opening l5 closed by a screw plug I6. Said chamber 13, furthermore, has'opposite walls H and I8, and a transverse partition [9 interconnecting said walls, and formed with a central valve opening 20.

Attached to wall I'I, below the partition I9, is a pipe 2! connected to a fuel tank; and connected to the opposite wall If}, and above the partition l9 is a pipe 22 leading to the burners for the stove or range l0.

Extending through the pipe I2 is a vertical rod 25 formed with a valve head 26 at its lower end adapted to close the valve opening 26. Interposed between the valve head 26 and the plug I6, is a coil compression spring 21 to normally raise the rod 25 for opening the valve and permit passage of fuel from pipe 20 to the pipe 22.

Means is provided to regulate the position of the rod 25. To this end, there is fixed to the upper end of the pipe [2, a bracket 30 having an The chamber l3 opposite arm" 3l' extending to one side of the pipe I2. Extending from the arm 3| :is a horizontal arm 32 overlying the upper end of the pipe' l2, and extending from'the arm32; 'are a pair of upwardly extending arms 33' and 34yfor the purpose hereinafter appearing. I

Arm 32 is formed with an internal screw threaded opening 36 aligned with the pipe I2.

Screwed within said opening is a screw threaded member 31 formed with a slot at its lower end. Fixed to the. upper end of'the rod 25"isa head having a transverse flange 4! received within the slot 38.; p v

The screw threaded member 31 is formedwith anaxial smooth opening 43 extending down to the slot 38. At the upper-end of the'sc'rew threaded member 3! is a large head'45 which may be turned to adjust the position of said screw threaded member. "Slidabl'y mounted in' the opening 43 is a pin 46.- To" the'upper end'of the pin 46 is screwed a head 48. The lowere nd'of l the pin 46 contactsthe upper end of portion 4| of the rod 25. Pivoted to the-arm'34 is a-lever 50 having one arm of the head 46.

Fixed to the bracket 30 is an angulararm 52 7, having a'horizontal portion'53 and a vertical upwardly extending portion 54; Fixed to the upper 'end of the-arm 52 is a thermostatic unit 55 of the disc type. v

When the thermostatic unit 55 heats, the top of the disc expands and moves upwardly. The

second arm 56 of lever 50vcontacts the upper side of the thermostatic unit 55.

It will now be understood that as the heat from the range increases, the thermostatic unit 55 will expand and move upwardly to rotate the lever 50 in a counter-clockwise direction, to press down on the rod 25 to cut down on the fuel. When the heat decreases; the-spring 21 turns the rod 25 upwardly to increase-the valve open- Thus, the thermostatic burner flames.

Means is provided to regulate the thermostatic control unit. To this end, there is fixed to the arm 33,v a horizontal arm 6|]. Pivoted to the arm 60, as at 6|, is a curved bracket 62. v Pivoted to the outer end of the bracket 62 is a canopy 63 overlying the thermostatic unit. The vertical position of the canopy may be adjusted by swing- 55, will control the effectiveness of said unit.

5| contacting the-upper side control H regulates the mined by means of a bracket 65 fixed to the bracket 52 and having a vertical portion 66 marked with graduations 61. The verticalarm 66 is positioned alongside of the canopy to facilitate determination of the position of the canopy.-

It will thusbe seen that there is provided a device in which the several objects=of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth orshown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
